accidently updated to 4.3 HB still loads

I'm a total n00b here, but soft modded my wii at v4.2. I stupidly did not have priiloader installed and my sister unknowingly updated to v4.3. I've read all over here and found out that I am lucky that my Wii is still working.

The update was disc based from Lego: Pirates of the Caribbean. I just checked and Home Brew has not been removed and actually works, but usb loader gx does not work, wont even load. Do I need to re-softmod or is it safe to try and reinstall my old HB apps?

I looked for other instances of this happening and haven't turned up anyone else heaving this happen.
